In women who have symptoms, the most common symptoms of uterine fibroids include:

  • Heavy menstrual bleeding
  • Prolonged menstrual periods — seven days or more of menstrual bleeding
  • Pelvic pressure or pain
  • Frequent urination
  • Difficulty emptying your bladder
  • Constipation
  • Backache or leg pains

Rarely, a fibroid can cause acute pain when it outgrows its blood supply. Deprived of nutrients, the fibroid begins to die. Byproducts from a degenerating fibroid can seep into surrounding tissue, causing pain and, rarely, fever. A fibroid that hangs by a stalk inside or outside the uterus (pedunculated fibroid) can trigger pain by twisting on its stalk and cutting off its blood supply.

Fibroid location, size and number influence signs and symptoms:

  • Submucosal fibroids. Fibroids that grow into the inner cavity of the uterus (submucosal fibroids) are more likely to cause prolonged, heavy menstrual bleeding and are sometimes a problem for women attempting pregnancy.
  • Subserosal fibroids. Fibroids that project to the outside of the uterus (subserosal fibroids) can sometimes press on your bladder, causing you to experience urinary symptoms. If fibroids bulge from the back of your uterus, they occasionally can press either on your rectum, causing a pressure sensation, or on your spinal nerves, causing backache.
  • Intramural fibroids. Some fibroids grow within the muscular uterine wall (intramural fibroids). If large enough, they can distort the shape of the uterus and cause prolonged, heavy periods, as well as pain and pressure.

When to see a doctor

See your doctor if you have:

  • Pelvic pain that doesn't go away
  • Overly heavy or painful periods
  • Spotting or bleeding between periods
  • Pain consistently with intercourse
  • Enlarged uterus and abdomen
  • Difficulty emptying your bladder

Seek prompt medical care if you have severe vaginal bleeding or sharp pelvic pain that comes on suddenly.
